ROOFING-TILE.

SPECIFICATION forming part of Letters Patent N 0. 691,650, dated January 21, 1902.

Application filed January 18, 1901. Serial No. 43,699. (No model.)

scribed in Letters Patent No. 516,570, which I now own and which were issued to me on the 13th day of March, 1894, by which construction the respective tiles comprising the roof are formed of earthenware, glass, or other similar heavy material, which tiles are interlocked together and held in place b their own gravity.

By my present improvement the tiles are struck up or pressed out into the desired shape from thin sheet metal, their inner and outer surfaces being one the direct converse of the other, by which peculiar shape each tile in a course laps upon its neighbor in such course and each successive course above the first laps upon the one beneath it.

My improvements pertain more especially, first, to the peculiar construction of the respective tiles, and, second, to the angular sheet-metal fastening-pieces located at the junction of the overlapping edges of the tiles in the respective courses.

My invention is further explained by reference to the accompanying drawings, in whichv Figure 1 represents a plan view showing several tiles in position as they are interlooked together in forming a roof. Fig. 2 is a transverse section drawn on line w as of Fig. 1. Fig. 3 is a longitudinal section drawn on line y y of Fig. 1. Fig. 4 represents a top View of the angular fastening-piece. Fig. 5 is a section drawn on line 15 t of Fig. 4, showing the tiles of the roofing in dotted lines. Fig. 6 is a section drawn on line 'LtLt of Fig. 1.

Like parts are identified by the same reference-letters throughout the several views.

A represents the main body of the tile, which is hexagonal in shape, and its general external configuration is substantially like the external configuration shown in my said Patent No. 516,570. Extending longitudinally through the center of each tile is a ridge B. From the ridge B the metal is curved downwardly in opposite directions toward the right and left to the flanges C and E. The flanges E E curve downwardly, so as to overlap and cover up the flanges formed at the upper ends of the tiles of the respective tiers. The respective side flanges C and the top flanges 0 curve upwardly and then downwardly in the form of an inverted V, as shown upon the right, and left in Fig. 2, by which arrangement said side flanges C are adapted to overlap and interlock with corresponding side flanges of the next adjacent tiles in the course upon their respective sides, while the top flanges C and C are adapted to be overlapped by and interlocked with the lower downward-projecting flanges of the adj acent tiles of the next succeeding tiers above.

To provide for the engagement of the concave surfaces of the V-shaped flanges C C with the convex surfaces I of the fasteningpieoe G, a rectangular notch L is formed at the lower ends of said flanges C upon both the right and left hand sides of each tile, so that the vertical edges of the notches of the two opposing tiles are brought together at a line drawn verticallythrough the center of said fastening-piece, whereby the head of the nail J, which passes vertically through the fastening-piece, engages the respective edges K of said flanges without passing through the tiles. It will be obvious that when the tiles are thus secured in place the expansion and contraction caused by heat and cold will have no tendency to draw out or loosen the nails or fastening-pieces or to tear or injure the tiles.

In laying the tiles the lower series are laid first, beginning at the right, when the edges of eachsucceeding tile upon the left in the series overlaps its neighbor upon the right, as more clearly shown in Figs. 1 and 2. The

first series being thus laid, the lower ends of the next series, which are laid in like manner above it, overlap and cover the top flanges of the first series, whereby water flowing from each upper series is carried over the joints formed at the upper ends of the tiles of each succeeding series below it.

As heretofore constructed the tiles of the respective series were provided with downwardly-proj ecting angular lugs adapted to engage on horizontal cross-pieces secured to the roof, by which the tiles were retained in place when interlocked together. By my improvement the downward-projecting lugs of the tiles and the horizontal cross-pieces of the roof heretofore used are dispensed with, the same not being adapted to be used with my present form of sheet-metal tiles. present form of construction the angularlocking-piece G is located at the upper end of the junction of each pair of tiles in each series of the roof. The fastening-piece G is provided with a flat horizontal piece lI,whioh rests upon the tile-supporting surface, and is provided with a V-shaped angular flange I, corresponding in shape with the under surface of the angular flanges C of the tiles which overlap and engage upon it. The fasteningpieces G having been inserted beneath the contiguous edges of the tiles, as shown in Fig. 1, they are secured in place by the nail J, the head of which is driven down so as to engage upon the respective edges K K of the contiguous tiles. It will be obvious that the nail being thus inserted holds the locking-piece Gin place upon the root and prevents it from sliding upwardly or downwardly, while the head of the nail engages the respective edges K of the tiles and prevents them from being raised out of contact with the locking-piece, and the concave surface of the locking-piece, which is nicely fitted between the concave surfaces of the flanges O of the tiles, prevents said tiles from sliding upward or downward, whereby such a parts are all held rigidly in place. It will be understood that when the next succeeding series or course of tiles are laid they entirely cover up and obscure from view the lockingl pieces G and the heads of the nails J as well as the joints formed by the contiguous edges of the tiles at K K. The several tiles of the roof being thus laid, it will be obvious that they are all securely interlocked in such a manner that each successive course of tiles is 1 held in place by the next succeeding course above it and all are rigidly and securely held in place.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl in a metallic roofing, the combination with 1 a succession of courses of metallic hexagonal roo tin g-tiles, havinginversely-shaped interior and exterior surfaces, and provided with concave-convex marginal edges, adapted to be overlapped and interlocked together; of angular sheet-metal fastening-pieces interposed between the tiles and their support, said fastening-pieces being located at the upper end or the overlapping flanges of the two next adjacent tiles in the respective courses; and the concave-convex surfaces of the angular V-shaped elevations of said fastening-pieces i being adapted to conform in shape to, and enl gage in, the concave surfaces of the angular top flanges of the two adjacent tiles above l them; together with a fastening-nail inserted l centrally through said fastening-pieces, the head of which is adapted to engage the contiguous edges of the two adjacent tiles in the respective courses, all substantially as and l for the purpose specified.

in testimony whereof I aflix my signature 4 in the presence of two witnesses.
